1. Spyware

2. WHO ARE THEY?
Programs that secretly record what you do on your computer. They can be used for some perfectly legitimate purposes, but the majority of spyware is malicious. Its aim is usually to capture passwords, banking credentials and credit card details - and send them over the internet to fraudsters.

3. How they work?
When you browse on the internet you can get spyware ‘’accidentally’’ or you can download in with the file you want to get. They work quietly so you never know whether you have it or not. They're often distributed as 'shareware' or 'freeware' with minimal license restrictions in order to trap as many people as possible.

4. How to defeat them? You can use anti-spyware programs.
You can try not to install/download a spyware.
